b) because actual medical specialists, who in many cases have done almost 10 years extra worth of academic work compared to GPs, would I think be rather annoyed if GPs started waltzing around saying they too were medical specialists.
I think you're misinformed. Unlike Russ I haven't had a GP rotation yet, but I know they are specialists because "your type" of "real specialists" have told me so. No-one waltzes around saying anything, because no one really cares. They're defined as specialists and so are neurologists, oncologists, cardiologists, etc. It doesn't matter.
It is strange, though, that some of the academics teaching those of you who go on to become GPs/specialists etc earn a great deal less than what you will probably earn. What do you make of that?
Um, most of the people who teach me are actually doctors?
As for the researchers, yeah it is a big shame that they're not paid more, they do the ground-breaking work to advance many fields. But that's not a fault of the doctors? That's a fault of the Government and their issues with funding.
Yes, obviously. That was my point. That's one of the few reasons the other poster gave for GPs being highly paid. Note the words in my sentence 'the argument doesn't quite work out'
When you said that you used it exclusively for one of the "criteria", paramedics don't undergo 15 years of rigorous training, they don't usually part-take in medical research (some do, sure), they're not historically people who have been looked up to when someone is at their lowest point in illness (I mean historically, it was doctors or God, some would argue it still is a common perception).
Sure, like doctors, paramedics have long hours, they "save lives" in the emergency setting (only), and so forth. They're integral to the health system. In fact, you'll find similarities to what doctors do (or are perceived to do) in many other health professions, but the others just don't tick all the boxes that doctors do.
Is this is "fair"? I don't know, and it's not an issue that overly concerns me. I know how valuable nurses, paramedics, etc are and that's what matters to me.
so I can wear scrubs and show off my gainz 
Charming.
